描述 Description

The ST high voltage BST capacitor controller STHVDAC-253MTG is a high voltage digital toanalog converter (DAC), specifically designed to control and meet the wide tuning bias voltagerequirement of the BST tunable capacitors.
It provides 3 independent high voltage outputs, thus having the capability to control 3different capacitors. It is fully controlled through an RFFE serial interface.
BST capacitors are tunable capacitors intended for use in mobile phone application, anddedicated to RF tunable application. These tunable capacitors are controlled through a biasvoltage ranging from 0 to 24 V. The implementation of BST tunable capacitor in mobile phonesenables significant improvement in term of radiated performance, making the performance almostinsensitive to external environment.
